Just to let you know... I was in Petco last night, and the manager there told me that they were having another $1 per gallon sale starting this coming Sunday (April 2nd). So it might be a good time for you to run in there and get you a 40 or even a 75 gallon to use for QT and/or tank emergencies that leave you needing something to put all of your fish and coral in.
I was able to score a 75 and two 40 gallons in their last $1 per gallon sale. They are empty right now, but at least I'll have them on hand if I ever need them for an emergency in the middle of the night when everything is closed.
